(1) These failure rates assume that a module's inputs or outputs are represented by a single block in a reliability block diagram (the
single channel rates should be applied to the reliability block if the module is configured in Single Channel mode, the dual
channel rates should be applied to the reliability block if the module is configured in Dual Channel mode).
(2) Single channel output mode (1732ES-IB12XOB4 and 1732ES-IB8XOB8 only) is only valid for applications with Process Safety
Times ≥ 600msec OR with Demand Rates ≤ 1 Demand per Minute.
